-
-1998-07-14 Raja R Harinath <harinath@cs.umn.edu>
-
- * mkstemp.c (<stdint.h>): Systems that don't have `mkstemp'
- probably don't have <stdint.h> either. Will fix it with a proper
- autoconf test later.
-
-1998-07-13 Raja R Harinath <harinath@cs.umn.edu>
-
- * argp.h (ARGP_EI): Define to `extern __inline__', rather that
- `extern inline'. Since this code is inside an __OPTIMIZE__ check,
- I assume this is GCC, and __inline__ will work.
-
- * mkstemp.c: New file.

-
-Tue Jul 7 00:02:51 1998 Tom Tromey <tromey@cygnus.com>
-
- * argp-help.c: Don't include <malloc.h>.

- * gnomesupport-h.c: Removed. Doesn't work well in cross-compiles.
-
-1998-06-08 Martin Baulig <martin@home-of-linux.org>
-
- * Makefile.am (gnomesupport-h): When cross-compiling, this
- is build using `$(build_CC)' because it needs to run on the
- build system. Look at gnome-libs/configure.in to see how to
- get `build_CC'.
-
-Thu May 21 21:21:12 1998 Tom Tromey <tromey@cygnus.com>
-
- * gnome-argp.h: Unconditionally declare program_invocation_name
- and program_invocation_short_name; some systems define these but
- don't declare them.
-
-1998-05-20 Raja R Harinath <harinath@cs.umn.edu>
-
- * Makefile.am (INCLUDES): Define _GNU_SOURCE.
-
-1998-05-19 Raja R Harinath <harinath@cs.umn.edu>
-
- * gnomesupport-h.c (strerror): Emit declaration.
- * strerror.c: New file. Imported from GNU libiberty.
-
-1998-05-19 Martin Baulig <martin@home-of-linux.org>
-
- * vsnprintf.c (vsnprintf): Changed declaration of this
- function on systems defining __STDC__ to avoid clash
- with prototype in system header file.
-
- * vsnprintf.c (snprintf): Moved toward the end of the
- file, so that the compiler sees correct declaration for
- vsnprintf().
-
-1998-05-12 Kjartan Maraas <kmaraas@fib.hl.no>
-
- * argp-help.c (argp_doc): Backed out previous "fix". :-)
- As pointed out it was dead wrong.
-
-1998-05-09 Kjartan Maraas <kmaraas@fib.hl.no>
-
- * argp-help.c (argp_doc): Removed a compiler warning.
-
-1998-04-14 Raja R Harinath <harinath@cs.umn.edu>
-
- * gnomesupport-h.c (main): Make gnomesupport.h include stddef.h
- unconditionally.
-
-1998-04-13 Raja R Harinath <harinath@cs.umn.edu>
-
- * scandir.c (<sys/types.h>): Include.
- * gnomesupport-h.c (!HAVE_SCANDIR): Do all the `dirent' wrangling
- only if `scandir' is needed. Also, include <sys/types.h> in all
- cases.
-
-1998-04-13 Seth Alves <alves@twitch.cp.domain.net>
-
- * gnomesupport-h.c (HAVE_DIRENT_H): FreeBSD needs <sys/types.h>
- before <dirent.h>.
-
-1998-04-12 Raja R Harinath <harinath@cs.umn.edu>
-
- * Makefile.am (supportincludedir): Is now $(pkglibdir)/include.
- `gnomesupport.h' is a generated file dependent on the configure
- process. So, this seems a good place. The rest of the headers
- are also here just because I'm too lazy to maintain two separate
- include directories to search in for `libgnomesupport' stuff ;-)
- (supportinclude_DATA): New var. Has `gnomesupport.h'.
- (BUILT_SOURCES): Generate `gnomesupport.h'.
-
- * gnomesupport-h.c: New file. Used to generate `gnomesupport.h',
- which contains prototypes for many of the functions in
- `libgnomesupport'. This method is used to ensure that prototypes
- appear only for those functions that are provided by
- `libgnomesupport'.
-
- * scandir.c (alphasort): New utility function.
-
-1998-04-08 Raja R Harinath <harinath@cs.umn.edu>
-
- * scandir.c: Import from GNU libc.
- Remove assumptions that this file is compiled inside GLIBC.
- Here are the ChangeLog entries when I imported it originally into
- `gwp':
-
- 1998-02-08 Raja R Harinath <harinath@cs.umn.edu>
- * scandir.c (scandir): Revert change of `1998-02-07'.
- Don't use d_reclen, but fix the expression used to
- figure out the length.
-
- 1998-02-07 Raja R Harinath <harinath@cs.umn.edu>
- * scandir.c (scandir): Use `d_reclen' field to get length
- of record.
-
- 1998-02-06 Raja R Harinath <harinath@cs.umn.edu>
- * scandir.c: New file. Replacement function copied from
- glibc, edited to not step on implementation namespace.
-
-1998-03-28 Raja R Harinath <harinath@cs.umn.edu>
-
- * vasprintf.c (int_vasprintf): Imported from GNU libit-0.4.
- Applied a change that appears in `libiberty'.
-
-Fri Mar 13 21:30:34 1998 Tom Tromey <tromey@cygnus.com>
-
- * argp.texi: Imported from glibc.
- * Makefile.am (EXTRA_DIST): Added argp.texi.
-
-1998-03-12 Raja R Harinath <harinath@cs.umn.edu>
-
- * Makefile.am (noinst_HEADERS): Don't install argp-fmtstream.h and
- argp-namefrob.h. They are used only to compile `argp' and not for
- general usage.
-
-1998-03-11 Raja R Harinath <harinath@cs.umn.edu>
-
- * getopt.h: Don't mention getopt() for C++. (Local fix).
-
- * vsnprintf.c: Actually fill it in. It is from
- <URL:http://theos.com/~deraadt/snprintf.c>, with one small fix to
- actually make it compile.
-
-1998-03-09 Raja R Harinath <harinath@cs.umn.edu>
-
- * easy-vsnprintf.c: New file. Provides (v)snprintf as simple
- wrappers to `__vsnprintf'.
- * vsnprintf.c: New file. Empty for now.
-
-Sun Mar 8 17:13:33 1998 Tom Tromey <tromey@cygnus.com>
-
- * Makefile.am: Rewrote. Library now named libgnomesupport, now
- installed if Gnome support code is built.
-
-Sat Mar 7 00:03:26 1998 Tom Tromey <tromey@cygnus.com>
-
- * gnome-argp.h (__mempcpy): New define.
-
- * strnlen.c: New file from glibc; needed by strndup.c.
-
-Fri Mar 6 20:10:55 1998 Tom Tromey <tromey@cygnus.com>
-
- * argp-fmtstream.h (__attribute__): Define unless using gcc.
- * argp.h (__attribute__): Define unless using gcc.
-
- * argp-help.c, argp-parse.c, argp.h: Imported new versions from
- glibc, while preserving local changes.
-

-
- * Makefile.am (noinst_HEADERS): Added argp-fmtstream.h,
- argp-namefrob.h, argp.h, gnome-argp.h.
- (EXTRA_DIST): New macro.
-
-1998-02-18 Raja R Harinath <harinath@cs.umn.edu>

-This directory has files from two "vendors". There are, thus, two
-vendor branches
-
- 1.1.1 GNU
- 1.1.2 SNPRINTF_de_Raadt
-
-The files that have "vendor" versions are:

- argp-fmtstream.c GNU
- argp-fmtstream.h GNU
- argp-fs-xinl.c GNU

-
-To find out the list of changes made against a "vendor" revision, you
-can say
-
- cvs diff -r <vendor-branch-tag>
-
-When any of these files are changed by the vendor, they can be
-reimported. At the time of importing, please make sure you use the
-correct branch revision and vendor tag.
-
-So, if you are importing changes to any of the `GNU' files, please use
-
- cvs import -b 1.1.1 gnome-common/support GNU <new-release-tag>
-
-If you are importing changes to "SNPRINTF_de_Raadt" files, please use
-
- cvs import -b 1.1.2 gnome-common/support SNPRINTF_de_Raadt <new-rel-tag>
- ^^^^^^^ ^^^^^^^^^^^^^^^^^^^

-
-Good places to get "support" functions:
-
-`libgnomesupport' is essentially a `glibc' emulation library, and hence
-`glibc' itself is a good source. However, some of the functions cannot
-be easily ripped out and put here (esp. any of the stdio-derived
-functions). Other places are:
-
-* libiberty from your friendly Cygnus source distribution, e.g.,
- binutils, gdb. The only caveat is that these cannot be used drop-in:
- you have to remove references to other files in the Cygnus tree &c.
-
-* libit, which appeared briefly on ftp://alpha.gnu.org
-
-* Jim Meyering's collection from his `fileutils'/`sh-utils'/`textutils'
- packages

- variable POSIXLY_CORRECT, or using `+' as the first character

- so that eventually all the non-options are at the end. This allows options
- to be given in any order, even with programs that were not written to
- expect this.
-
- RETURN_IN_ORDER is an option available to programs that were written
- to expect options and other ARGV-elements in any order and that care about
- the ordering of the two. We describe each non-option ARGV-element
- as if it were the argument of an option with character code 1.
- Using `-' as the first character of the list of option characters
- selects this mode of operation.
-
- The special argument `--' forces an end of option-scanning regardless
- of the value of `ordering'. In the case of RETURN_IN_ORDER, only

-/* Scan elements of ARGV (whose length is ARGC) for option characters
- given in OPTSTRING.
-
- If an element of ARGV starts with '-', and is not exactly "-" or "--",
- then it is an option element. The characters of this element
- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns -1.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of
- handling the non-option ARGV-elements.
- See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most
- recent call.
-
- If LONG_ONLY is nonzero, '-' as well as '--' can introduce
- long-named options. */

-NAME

-
-SYNOPSIS
-
- static void init_error_tables ();
-
-DESCRIPTION
-
- Using the error_table, which is initialized at compile time, generate
- the error_names and the sys_errlist (if needed) tables, which are
- indexed at runtime by a specific errno value.
-
-BUGS
-
- The initialization of the tables may fail under low memory conditions,
- in which case we don't do anything particularly useful, but we don't
- bomb either. Who knows, it might succeed at a later point if we free
- some memory in the meantime. In any case, the other routines know
- how to deal with lack of a table after trying to initialize it. This
- may or may not be considered to be a bug, that we don't specifically
- warn about this particular failure mode.

-SYNOPSIS
-
- int errno_max ();
-
-DESCRIPTION
-
- Returns the maximum errno value for which a corresponding symbolic
- name or message is available. Note that in the case where
- we use the sys_errlist supplied by the system, it is possible for
- there to be more symbolic names than messages, or vice versa.
- In fact, the manual page for perror(3C) explicitly warns that one
- should check the size of the table (sys_nerr) before indexing it,
- since new error codes may be added to the system before they are
- added to the table. Thus sys_nerr might be smaller than value
- implied by the largest errno value defined in <errno.h>.
-
- We return the maximum value that can be used to obtain a meaningful
- symbolic name or message.
